An empty sea of darkness, the Void serves as an "Astral Plane" for the cosmologies. Deep Shadow leads into slivers of the Void that reach between the cosmologies, and which can be traveled between these cosmologies. However, the Void has its own inhabitants, and once you get to its wide-open spaces you will meet the deadlier ones for yourself.

Energy Dominance: Some places in the void have the minor negative-dominant trait, and it is rumored that somewhere in the Void is a place similar to the Temporal Energy Plane that is also negative dominant. However, the Void as a whole has no energy dominance.

The most famous link the the Void is that created by the Arcanists. Within Deep Shadow, there are rifts that lead into the Void. These rifts appear little different than the surrounding darkness, so it is possible for a traveler to enter the Void without realizing it until they see a Comet Being or similar landmark. It is said that Planar Rifts - huge orbs of darkness that suck in matter around them - lead to the Void, and that at the heart of the Negative Energy plane there is one such massive rift.

There are few inhabitants of the plane. The most common are the Comet Beings, said to be the only indigenous species - and even they may not be native. Other inhabitants include the Infinity and the Void Dragons, both examples of the physical corruption this plane can bring upon creatures.

Movement and combat are the same as on the Material Plane, except on the surface of particularly massive Comet Beings. They can alter the strength of gravity at will, but usually keep it at a strength roughly equal to that of Earth.

Within the Void, there are places that can suck the life out of you. The most minor of these places are simply patches with the Minor Negative Dominance trait, but most come with severe storms. These storms use the rules for severe weather in the Elemental Plane of Air, along with minor negative dominance. Every so often, you will come upon a supernaturally severe storm. This storm uses the rules for a Storm of Vengeance, except that every possible effect is present constantly, and it also has the major negative dominance trait.

The Infinity have built up a large number of cities throughout the Void. Spherical structures of tubes and strange machines, they appear more as factories then as cities. The tubes are pneumatic, and the Infinity use them for transportation throughout the machines, in which they eat, sleep, spawn, train, and build battle and work machines. These tubes are 2 and a half feet in diameter, meanng a Medium creature can squeeze though with some difficulty.
